+# Real Application Testing
+Real Application Testing comes in two flavors - Database Replay (DB Replay) and SQL Performance Analyzer (SPA). Both can be used independently of each other but are also a good complement. 
+With SQL Performance Analyzer you can check the SQL performance. It focuses on detailed statement analysis of a defined SQL workload made available via a SQL Tuning Set (STS).
+Statements from a SQL workload can be tested and compared and tuned if necessary.
+
+Database Replay can be used to capture a real workload on the production system and replay it on a test system with the exact timing, concurrency, and transaction characteristics of the original workload. This enables you to test the effects of a system change without affecting the production system.
